Refactor TCP socket connection calls in tests and implementation

- Replaced instances of `TCPSocket::setup()` with `TCPSocket::connect()` across multiple test files and the dashboard client implementation to standardize connection handling.
- Updated connection logic to improve clarity and consistency in socket management.
